The invention relates to reactive dyes of the formula ##STR1## wherein D is the radical of a dye of the monoazo or polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide series, each of R.sub.1 and R.sub.2 independently is hydrogen or an unsubstituted or substituted C.sub.1 -C.sub.4 alkyl radical, X.sub.1 is an unsubstituted or substituted aminofluoro-s-triazine radical, and X.sub.2 is a heterocyclic reactive radical which is attached direct to the radical D through the --N(R.sub.2) bridge member, excepting an unsubstituted or substituted aminofluoro-s-triazine. These dyes are particularly suitable for dyeing and printing cellulosic fibre material by the cold pad-batch method and give dyeings and prints of good fastness properties and high tinctorial strength.
本发明涉及公式##STR1##的响应染料,其中D是单偶氮染料或多偶氮染料,金属络合偶氮染料,蒽醌,酞菁,福马赞,偶氮亚甲基,二氧咔嗪,苯噁嗪,亚甲基双(苯并咪唑),三苯基甲烷,黄色素,噻吩,硫氧噻吩,硝基芳基,萘醌,芘醌或苝四甲酸二酰亚胺系列染料的基团,R.sub.1和R.sub.2各自独立地是氢或未取代或取代的C.sub.1-C.sub.4烷基基团,X.sub.1是未取代或取代的氨基氟基三嗪基团,X.sub.2是异环反应基团,该基团直接通过--N(R.sub.2)桥连成员连接到基团D上,但不包括未取代或取代的氨基氟基三嗪。这些染料特别适用于通过冷垫-批处理法染色和印刷纤维素纤维材料,并提供具有良好耐久性和高染色力的染色和印刷。
